ubuntu 11.04

Having trouble with my b43 wireless after installing ubuntu 11.04. I found this page and got my wireless up and running in no time

from another forum, http://ubuntuforums.org/showthread.php?t=1604868,
I did this,

Code:

 sudo apt-get --purge remove bcmwl-kernel-source  sudo apt-get install patch    sudo apt-get install bcmwl-kernel-source

that didnt work then i tried this

Code:

sudo apt-get update sudo apt-get --reinstall install bcmwl-kernel-source

that still didnt work but when I entered the code below

Code:

sudo modprobe b43

The button worked, the wireless worked, and everything was awesome, until I switched my laptop off and restarted. The button and wireless didn't work.
But low and behold, after typing

Code:

sudo modprobe b43

The button and wireless were back up and running.

Now to make sure it all works from start up

echo 'b43' | sudo tee -a /etc/modules

And this has now solved all my problems.
